Ensure you are not logged into multiple Salesforce instances.

Being logged into multiple instances of Salesforce (Sandbox, Production, Development, and so on.) in the same browser is always a bad idea.Try logging out of all instances except the one in which you are working and run the solution again.

Be sure you have not exceeded product data limits.

If you are experiencing an issue, it is possible you have exceeded the limits of what the product is able to do. Check the Product Data Limits to ensure you are within the bounds of what the application is able to do.

Determine where the problem is.

If you have reached this point in troubleshooting and have not solved your issue it is time to run a test to determine where the problem is. The problem likely lies in one or more of the following areas: the Composer URL, the Composer Template, or Salesforce permissions.

If the Composer window returns an error, the problem likely lies with the Composer URL.

If the document merge is successful, the problem likely lies with the Composer template.

If the problem lies with the URL, see the information below about analyzing the Composer URL.

If the problem lies with the template, see the information below about deconstructing the template.

Analyze the Composer URL.

The Composer URL tells you a lot about the solution. Access the Debug URL and copy it into Notepad or another program where you can view it. Look for illegal characters (spaces, *, & anywhere other than at the beginning of a parameter, %, pipe ( | ), ;, etc.), fields that are not updating correctly, or formulas that don't seem to be working. If you cannot solve the problem yourself, you will likely need to provide the Debug URL to your Business Analyst anyway, so you are moving in the right direction.

Deconstruct the template.

With larger templates, we recommend removing one page/slide of the template at a time and running the merge process again. For smaller templates, you can remove a paragraph at a time. Keep doing this until you run a successful merge. At that point you have likely identified the source of the error in the template and you can work on correcting it.

View Data Workbook

If the problem with your template is that data are not merging, the View Data Workbook is a handy tool to help identify the issue. From the Tools & Settings drop down on the Composer user interface you can select the View Data link, which downloads an Excel workbook that contains all of the data Composer has retrieved for your solution.

A simple rule of thumb: if the data you expect to see in your template are not in the View Data Workbook, they are not going to merge into your template.

If data are not in the View Data Workbook: the problem likely lies with the data source retrieving the data (i.e. the Salesforce report or Conga Query). Check the reports or queries for your solution to ensure they are returning data properly.

If data are in the View Data Workbook: the problem likely lies with the template. Check the detail region to ensure it is properly formed with TableStart and TableEnd merge fields (and make sure the proper dataset name, i.e. the alias, is referenced).

Check Salesforce permissions for all end users.

If you are a System Administrator, you can use the Login as User functionality in Salesforce to run solutions, download the View Data Workbook, and review error messages as end users, which will be helpful in identifying the permissions issue.

Field Level Security (FLS) is the most likely culprit when it comes to Salesforce permissions. See the above article for more information about FLS.

Investigate error messages.

Lastly, if you are receiving an error message, search for your error message on the support site. You can review all documented error messages in Composer Error Messages. Error message articles contain information about what is causing the issue as well as steps to address it.
